Floating Architecture

This is my first architectural render in Blender. The architecture is based on the Gherkin in London and the Geodesic dome. The pentagonal leaflike structures in the foreground are actually segments of the Geodesic dome and they function as study-centres for marine life. The buildings on the hexagonal floating deck are the apartments where the students of marine life can spend the night. It is a completely fictional design, I just had an image in my mind and tried to realize it with the Blender.
